Description

The present invention relates to a cleaning sponge having improved detergent retention.

In general, when washing dishes such as dishes and teacups after meals, and cooking utensils such as pans and pans used during cooking, attach a detergent for washing the dishes to the surface of the washing sponge. The surface is rubbed and washed with water.

However, the sponge has a porous surface so that the detergent can be soaked into the surface, but since it is used constantly with running tap water or with water, the detergent impregnated on the surface is gradually washed away and washed. There was a problem that the effect disappeared in a short time.

The present invention solves the above problems and provides a cleaning sponge in which detergent gradually oozes out from the inside and can be washed over a long period of time, thereby saving the amount of detergent used.

The cleaning sponge according to claim 1 of the present invention is characterized in that a slit reaching inward from the surface of the sponge is formed, the slit portion is opened, and the inside of the sponge is impregnated with a detergent therefrom. Is.

The cleaning sponge according to claim 2 of the present invention is characterized in that a slit reaching inward from the surface of the sponge is formed in a cross shape.

According to the cleaning sponge according to claim 1 of the present invention, since the slit portion is opened and the inside of the sponge is impregnated with the detergent, the detergent gradually exudes from the inside of the sponge to the surface when washing. Thus, the cleaning effect can be maintained for a long time, and the amount of detergent used can be greatly saved.

According to the cleaning sponge of the second aspect, since the slit is formed in a cross shape, a gap is formed regardless of whether the sponge is curved in the vertical or horizontal direction, and the detergent can be easily injected.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 denotes a cleaning sponge. A polyurethane foam 2 having a rectangular parallelepiped shape is provided on the upper surface, and a nylon nonwoven fabric 3 is integrally bonded to the bottom surface. A linear slit 4 is formed on the upper surface of the polyurethane foam 2 so as to reach the inside along the longitudinal direction thereof.

As shown in FIG. 2, the cleaning sponge 1 having the above structure is held in a hand 5 and pushed with the index finger or middle finger to push up the central portion of the nylon nonwoven fabric 3 on the bottom surface. The slit 4 formed on the surface of 2 widens greatly to form a gap 6. In this state, the detergent 8 is poured from the tip of the kitchen detergent container 7 into the gap 6 and then the slit 4 is closed. Since the slit 4 is formed so as to reach the inside along the longitudinal direction of the polyurethane foam 2, the detergent 8 is in a state of being soaked into the porous interior. When the surface of the dish 9 is rubbed while applying water as shown in FIG. 3, the detergent 8 oozes out and foams, and the surface of the dish 9 can be cleaned by removing dirt.

As described above, the detergent 8 gradually exudes from the inside of the polyurethane foam 2 to the surface, so that the cleaning effect can be maintained for a long time. About twice as much tableware can be washed. That is, the detergent 8 to be used can be saved greatly, which is extremely economical.

FIG. 4 shows another embodiment of the present invention, in which a linear slit 4 reaching the inside along the longitudinal direction is formed in a cross shape on the upper surface of the polyurethane foam 2. This can form the gap 6 regardless of whether the polyurethane foam 2 is curved in the longitudinal or lateral direction, and the detergent 8 can be easily injected.

In the above description, the polyurethane foam 2 and the nylon nonwoven fabric 3 are integrally formed. However, the present invention can be applied to a cleaning sponge formed only of the polyurethane foam 2. The sponge is not limited to polyurethane foam but may be other foamed plastic.

1 is a perspective view of a cleaning sponge according to an embodiment of the present invention. It is a perspective view which shows the state which opened the slit of the sponge for washing | cleaning of FIG. 1, and inject | poured the detergent into the clearance gap. It is a front view which shows the state which wash | cleans the dish using the sponge for washing | cleaning of FIG. It is a perspective view which shows the sponge for washing | cleaning which formed the cross-shaped slit by other embodiment of this invention.
